This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Touching?
A team at Umea University (Sweden) have investigated why human touch seems so exquisite (https://www.theguardian.com/science/2021/mar/15/top-tips-study-sheds-light-role-fingerprints-sense-touch). The study found the receptive fields for mechanoreceptor neurones, covered several fingertip ridges. In some of these areas, however, deflection of a single ridge, could evoke a neural response. We have very many nerve fibres, with very small receptive fields, at our fingertips!
